He seems to think our 4-3 under alignment isn't a 4-3 under because Jelly is lined up in the 4 tech instead of the 5. Just semantics. Maybe if we actually had a 5 tech DT they would be lined up in the 5 tech position.

The defense that Pete Carroll now employs uses the basic tenets of the Monte Kiffin 4-3 Under defense and mixes in a variation originally pioneered by the legendary George Seifert in San Francisco. Seifert wanted to create mismatches against the opposing offensive line so he started using his weakside defensive end to rove around and rush the passer from a two-point stance (standing up position). This was the beginning of the "Elephant" position and one that Carroll uses today. We also see this position called the LEO, and in the Hawks' defense can rush standing up or in a three-point stance. Notice standing up or three-point stance. You're arguing semantics.
